BANGKOK (The Nation Thailand/ANN): Prime Minister Srettha Thavisin expressed appreciation for the work local agencies in Chiang Mai are doing to tackle the scourge of ultra-fine dust, resulting in much-improved air quality in the province.
Speaking to reporters after returning from Chiang Mai on Sunday, Srettha said a weather station in Chiang Mai measured PM2.5 at only 12 micrograms per cubic meter of air (μg/m3), which was far lower than previous levels of ultra-fine dust.
